Each network adapter has multiple routes for different destination
addresses. Each route has its own metric value, which is the last
number shown.
Your wired adapter has these routes:
0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.20 1
192.168.0.0 255.255.255.0 192.168.0.20 192.168.0.20 20
192.168.0.20 255.255.255.255 127.0.0.1 127.0.0.1 20
Your wireless adapter has these routes:
0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.21 1
192.168.0.0 255.255.255.0 192.168.0.21 192.168.0.21 25
192.168.0.21 255.255.255.255 127.0.0.1 127.0.0.1 25
For each adapter, those routes are:
0.0.0.0 0.0.0.0 = default route, used to reach addresses not on the
LAN, such as Internet sites
192.168.0.0 255.255.255.0 = subnet route, used to reach addresses on
the LAN
192.168.0.x 255.255.255.255 = host route, indicating that the IP
address is local to this computer, as shown by a gateway address of
127.0.0.1
All of an adapter's routes usually have the same metric, but your
adapters have a different metric for the default route than for the
subnet and host routes. That could be because a default gateway and
metric have been manually entered in the corresponding network
connection's Properties > Internet Protocol (TCP/IP) > Properties >
Advanced > Default Gateways.
Since both adapters have the same metric for the default route, it's
not possible to predict which adapter will be used for Internet
access.
Subnet access will use the wired connection, since its subnet route
has a lower metric.
